Application October 11, 1949, Serial No. 120,730

2 Claims.

This invention relates to an improved le holder, the primary object of the invention being to provide a more efficient and serviceable device of this kind which can be made in an attractive and practical form at relatively low cost.

Another important object of the invention is to provide a le holder of light weight and small bulk which closely conforms to the file, is readily adjustable for files of different lengths, and which serves to prevent contact of the lile with the hands or with dirt on the work bench or the like.

Other important objects and advantageous features of the invention will be apparent from the following description and the accompanying drawings, wherein, merely for purposes of illustration herein, a specific embodiment of the invention is set forth in detail.

In the drawings:

Figure 1 is a top plan view;

Figure 2 is a vertical longitudinal section, an associated file being shown in dotted lines;

Figures 3 and 4 are transverse vertical sections taken on the lines 3--3 and 4-4, respectively, of Figure 2.

Referring in detail to the drawings, wherein like numerals designate like parts throughout the several views, the illustrated file holder comprises a cylindrical cross-section, tubular handle 5 having a modified hourglass shape, and being closed at its forward end by a wall 6 formed with a transverse, diametrical slot l. Above the slot 'I the wall 6 and the forward end of the handle 5 are formed with a preferably-integral, longitudinal extension 8 involving a forwardly-projecting bar S having a dovetail slot or channel IIJ in its lower or under side I I.

Near its forward end the bar 9 has thereon a threaded boss I2 with a wing bolt I3 threaded therein and traversing a hole I4 extending through the bar 9 into the channel IIJ to engage the top or upper side of a dovetail I5 on the extensible bar IE5y which slidably engages the dovetail slot I0 for locking the extensible bar I6 in a selected, adjusted position, in accordance with the length of a flat mill file I1 whose shank I8 is positioned rearwardly through the handle slot 'I and whose forward end I9 is engaged with a pair of laterally-spaced, downturned hooks 20, 20 formed on the forward end of the extension barr I6.

The forward end of the stationary bar 9 has an upturned terminal 2| against which one hand is adapted to be applied in guiding and operating the device, with the other hand grasping the handle 5.

It will be observed that no matter in what position the device is laid upon a flat surface, the le I'I cannot come into contact therewith; and that in the operation of the file the hands cannot come into contact with the le in ordinary course.

What is claimed is:

l. A holder for a file comprising a handle having a forward extension including a stationary bar terminating at its forward end in a hand hold, an extension bar having a portion coextensive with and slidably engaged with said stationary bar, said extension bar terminating at its forward end in a downturned hook for engagement by the forward end of a file positioned beneath and along said stationary and extensible bars, clamping means for fixing Said extensible bar in adjusted relation to said stationary bar, and holding means on said handle for holding the shank of a le.

2. A holder for a file comprising a handle having a forward extension including a stationary bar formed with a channel at its under side and terminating at its forward end in a hand hold, an extensible bar beneath and extending along said stationary bar and slidably engaging said channel, clamping means operating between said bars for clamping said extensible bar in adjusted relation to said stationary bar, said handle being formed with a le shank-accommodating slot and the forward end of said extensible bar having a hook for engaging the forward end of a file whose shank is positioned in said handle slot.
